Off Line Bottle Visual Inspection Machine With Auto Rejection & Counting System

Off Line Bottle Visual Inspection Machine with Auto Rejection & Counting System

Inspection principle

The solution uses 8 sets of high-resolution industrial cameras and high-performance strobe light sources to conduct all-round visual inspection for the appearance defects of bottle products. The inspection speed is 120 pieces per minute. Unqualified products can be automatically removed online.

The whole set of testing equipment includes mechanical parts, visual electronic hardware and testing system software. The entrance and exit of the testing machine can be integrated with the customer's on-site conveyor line, and can be connected with upstream and downstream production equipment (such as leak testers, balers and other equipment, etc.).

Inspection notes:

Black spots, stains, hair, and impurities (different colors) will be analyzed and processed according to the black spot detection index. The difference between the gray value of this item must be greater than 15, which can be effectively detected. If the sample has transparent oil stains or light-colored black spots, and the gray value contrast difference value is low (less than 15), the detection effect cannot be achieved.

If the product structure is special, in the actual inspection application, there will be a certain detection blind area in the structural overlapping area of the plane lens imaging (such as the area under the thread and the lifting ring, the angle area between the steps of the bottle body, etc.), and the image acquisition cannot reach this blind area. , so it cannot be effectively detected.

Application of camera

• For bottle mouth plane detection, a set of industrial cameras is installed above the bottle mouth, and with the use of visual light source, the bottle mouth plane image is collected for processing.
• For the inspection of the inner wall of the bottle mouth, a set of industrial cameras are installed above the bottle mouth, equipped with a lens inside the ring, and used in conjunction with the use of visual light sources, to collect images of the inner wall of the bottle mouth for processing.
• For the detection of the outer bottom of the bottle, the bottle body is suspended in the air through a specific conveying mechanism, and a set of industrial cameras are installed below, and the image of the outer bottom of the bottle is collected for processing in conjunction with the use of visual light sources.
• Bottom detection in the bottle, a set of industrial cameras are installed above the bottle mouth, and with the use of visual light source, the image of the bottom in the bottle is collected for processing.
• For the side inspection of the bottle body, 4 sets of industrial cameras are installed around the bottle body to form a 360-degree ring surface inspection. With the use of visual light source, the side image is collected and processed systematically.
